BOOT OR SHOE.

SPECIFICATION forming part of Letters Patent No. 259,230, dated June v6,1.882.

Application filed May 23, 1881.

The invention consists in a boot or shoe having an insole composed ofsheet metal and leatherhoard, the metal i'astenings uniting the outersole and upper being driven through the metal part of the inner sole, ashereinafter described. When leather-board alone is used as an insole itis liable to become soitened by moisture, when it will lose its holdupon the astening-pegs and allow the upper to become separated from thesole. This I obviate by placing a metallic lining-sole beneath the sheetof leather-board, or between two sheets of leather-board, as the casemay be, it protect- 'ing the leather-board from moisture, and itseltaffording a iirm hold for the nails or fastenings. t Y Y In order toprevent the edges of thel metallic sole from cutting the upper drawnover them, it is made of a smaller size' than the leather-board partsthereof, the ed ges ot' which overhang the said metallic sole, 'andthemselves come in contact with the upper, which is thus protected fromthe said metallic portion of the insole,

Figure l is a vertical cross-section ot' a shoe provided with myinvention; Figs. 2 and 3,

plan views ofthe metallic sole, showing different methods of slitting itfor the purpose of reducing the stiffness of the shoe.

The upper a is drawn over the edges ofthe insole bin the usual manner,and provided with an outer sole, c, connected with the said insole, asby the nails d, which pass through the edges of the upperand are upsetor clinched at the inner surface of the insole b iu the'.

usual manner to connect the sole and upper firmly together.

The insole b is composed of a metallic plate,

(No model.)

2, placed between two sheets of leather-board, 3 4, cut in proper formin the usual manner. In order to prevent the upper from being cut andworn by the edge of the metallic portion 2 of the insole, the saidmetallic portion is made smaller than the leather-board3 4, so that theedges of the latter overhang the former, and themselves receive theupper a, preventing it from coming in Contact with the edge of the saidmetallic portion 2.

Themetallic portion 2 ot' the insole may be provided with transverseslits 5, which may either extend across its middle portion, leaving theedges intact, a'svshcwn in Fig. 2, or may extend alternately from theopposite sides, as shown in Fig. V3, passing from one edge across nearlyto the other.

The portion 4 of theleather-hoard at the under side of the insole may beomitted, if desired. The metallicportion 2of the insole protects theleather-board 3 above it from the effects ot' moisture penetrating theouter sole, Vand thus prevents it from softening to permit the nails dto draw through, while the said metal portion itself affords a firm holdfor the said nails. f

A sole may be constructed in this manner having the advantages ot' aleather sole at much less cost.

I claim- As an improved article of manufacture, a boot or shoeconsisting of an upper, o'uter sole, and inner sole, placed within theshoe above the inturned edges of the upper, the said inner sole beingcomposed of metal and leatherboard, the latterl being extended at itsedges beyond the edges of the metal, the sole-fast enings uniting theupper and the outer sole passing through `both the metallic andleatherboard portions pt' theinner sole, as shown and described.

In testimony whereofI have signed my name to this specication in thepresence of two subscribing witnesses.
